Wink Re: COPO Stands for what?

Near the front of my GM parts catalogue it says Central Office Production Order. There is even a separate COPO catalogue, mostly truck stuff, but there is no mention of the COPO cars at all. Strange. COPO was used mostly for truck and fleet stuff such as odd ball taxi or police combinations. GM already had the L72 427 so it was no big deal for them to put it in a Chevelle or Camaro. Same went for the LT1 for the 1970 Novas. Most all of the car stuff was off the shelf.
Danny's el Camino has a real COPO look to it.

Re: COPO Stands for what?

It is easy to get confused with the term “COPO” because many magazines and web sites use the term “COPO Chevelle” to mean a factory built 427 425hp Chevelle but there could be all kinds of non high performance Chevelles with a COPO option. As Keith said there were many COPO options so the term “COPO” should be used with its code number and description to tell what the option is.
COPO just means Central Office Production Order, which is a way to order an option that could not be ordered by RPO (Regular Production Order). For example a Chevelle with the option RPO L78 is a 396 375hp engine which you could have ordered through the normal dealer process but the option COPO 9562 is a 427 425hp high performance Chevelle that needed a special order process and approval to build. There were COPO option code numbers for all kinds of equipment for special vehicle builds. I have seen a police car build sheet that had a COPO code for a special alternator and wire harness. Most COPO options were not for high performance vehicles but that is what gets all the attention.

Thank you, sir! That was the original intention. Plus, since they never made a COPO elky, I couldn't be accused of trying to make a "clone" of one.

Here it is at CB04 with ralleys, no 454 emblems, etc.

Thumbs up Re: COPO Stands for what?

We're going with the silver paint and COPO look with our el Camino as well. The blacked out grille and tail end, along with the SS hood and wheels just give such a nice clean look. The red sure looks great.

Re: COPO Stands for what?

You mean you couldn't "special order" a 427 hemi with aluminum heads in a '69 Chevelle? A guy at a cruise told me you could.

Actually , I'm sure they made several. Any special paint order, or special engine had to go through the channels, and ended up in C.O.P.O for approval. My dad has a 1986 4x4 truck , that is a C.O.P.O, as it was ordered in a special color.

You're exactly right, Doug. Should have said "an elky with the COPO 9562 package".

Question Re: COPO Stands for what?

How Would It Read On Your Build Sheet Or Cowl Tag As A Copo. I Have A #0382 In The Lower Right Corner Of My Cowl Tag And It Is On My Build Sheet In The Upper Right Hand Corner. No One Seems To Know What It Means. Someone Once Told Me That It Meant Some Type Of Special Order. Does Anyone Know Thanks

Re: COPO Stands for what?

There were many COPO option code numbers (not all high perf options) that would appear on the build sheet with the other options.
If you can post a picture of your build sheet maybe some on here can help.

Re: COPO Stands for what?

A COPO Chevelle build sheet will show the MP or MQ engine and KQ 4.10 rearend. The COPO option code eg. 9566AA will show up in the lower area with the other options.
